Rodin Theory & Coils

[ronotte]

@Rosphere,

WELL DONE, please go on with your implementation, in the mean time I'm preparing to do the same, just trying to find the correct annular plastic support. I'm courious to see the difference with the Caduceus I tested some time ag?. In those tests I were able to take out about 60W on a 230V lamp (no OU but near). I still have the test pictures that I will compare.

I'm not sure about what you want to do with the second opposing winding that you are going to wind, would you be so kind to detail?  With Caduceus coil I used it as a single coil but with an inner 90 degrees collector connected directly to lamp load.

Hello, Roberto.  I hope that you are well.

Yes, It is difficult to describe with words alone what my question is regarding the winding of the second wire.  Since I am at work now, I have no time to make and post a drawing for clarity.  Referring to the figure that bocas posted above, I already have the red wire wound as shown (1 7 4, 1 7 4, 1 7 4,...) and my question is about winding the green wire.  There are two ways to wind the wire along the green path; to start-off winding over the top of the form (2 8 5, 2 8 5, 2 8 5,...) or to start off winding under the bottom of the form, (2 5 8, 2 5 8, 2 5 8,...).

Some have advised to wind the green wire in the same direction as the red wire and I can reverse the current if need be.  But this little voice inside keeps telling me to wind in the opposite direction.  I can not discern if this little voice is the voice of success or the voice of failure.  If I do wind in reverse and it turns out to be wrong, will swapping the current flow also work in this case?

I think the winding difference has to do with the direction of current flow from one wind to the next along the perimeter.  Perhaps I will make some detailed drawings showing what I mean after work today.  My issue is really quite simple, yet difficult to describe.  If you were in the same room with me and I had my coil in hand then I could show you what I mean in less than thirty seconds.  Perhaps I should make a short video clip.

rosophere,

first let me say great work on the coil!  i think i am beginning to catchup a little bit with your work and that post by boccus.

i  also agree with comster, that somewhere in the rodin videos, marko, said that the coil can be wound in the same direction because the math takes care of the problems.  i will continue to search, however a did find this quote in video five.  marko said, "linearity is what makes 3-d."  to me this says the same thing.  continue on in the same direction.  just my two cents worth.  at least if you keep going in the same direction you won't have to tear the whole coil back to foam.

wow Rosphere. that looks like a chore to build. Sure is preedy tho. Nice to see you around again.

Rosphere,

if I remember well the 'second winding' purpose is to allow  something like a bifilar approach: so possibility to cancel at a second level (?) the magnetic field or for signal extraction. None reported the use of second winding as tests run by JLN and Helwett & Packard have used only the Rodin as a single coil even if they have placed the second winding. Again NONE used the Rodin to provide power (in my knowledge) but only for behavior study. 

To summarize it could be useful wind both windings in the same direction, anyway this is what I'll do. Second I'll wind, as I've done with Caduceus coil, not not only one wire but rather 2 or 4 thin copper enamelled wire in parallel as I've already checked that this is far superior than the single wire run  (this in terms of output on lamp).

Again may be interesting to sneak a tick collector wire inside the annular form and try to collect power....

Now I'm still finding necessary components.....but I'll join you soon.

have fun

Roberto
